Microsoft Azure Virtual Machine Scale Set

This SAM application monitor template contains performance and statistics counters for monitoring Azure Virtual Machine, an on-demand, scalable computing resource.

Passwords for legacy Microsoft Azure application monitor templates and related application monitors are stored as plain text in the SolarWinds Platform database. SolarWinds recommends switching to Microsoft Azure API poller templates that leverage OAuth 2.0 authorization.”

Prerequisites

• PowerShell module (Azure, AzureRM) is installed before using this template.

  To install the Azure module, execute these PowerShell commands:

• Install-Module -Name Azure

• Install-Module -Name AzureRM

• To connect with the Azure account, you'll need the SubscriptionID, ApplicationID, TenantID, and Secret Key.Any Azure App (with its name and ID) having minimum role as Read Only

• Virtual Machine name for which metrics are being calculated.

• PowerShell 5.0 or later.

Credentials

• Login credential to access the Azure Portal, passed as script arguments per prerequisites (<SubscriptionID>, <TenantID>, <ApplicationID>, value=<Secret Key>, <Virtual Machine Name>, <ResourceGroupName>).
• Optional parameters can be passed to script argument:
• value=<Time Interval> - during which data must be fetched, in minutes. The default is 10 minutes.
• Number of retries as the second last argument; the default is 3.
• WaitTime as the last argument; the default is 0.5 seconds

Notes

• Run scripts with Administrator privilege on target system.
• The ApplicationID with which you are connecting to the Azure portal must be registered in Azure Active Directory as contributor role for the monitored application. See Add an Azure Active Directory app for cloud monitoring in the SolarWinds Platform.
